85202-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85202-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,0 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85202-83:
(7*8)+(6*5)+(5*2)+(4*0)+(3*2)+(2*8)+(1*3)=121
121 % 10 = 1
So 85202-83-1 is a valid CAS Registry Number.

A series of persistent 6-oxo- (4a-p) and 6-thioxoverdazyls (5a-g) could be obtained by dehydrogenation of corresponding 1,4,5,6-tetrahydro-1,2,4,5-tetrazin-3(2H)-ones (2a-p) and thiones (3a-g).This reaction can also be used for the preparation of diradica
